Love that sort of thing!
Reminds me of a time at a previous residence when I want downstairs to make coffee, and there was the shadowy image of a giant penis on the backdoor blinds - which was actually a shadow cast by an umbrella in its down-and-tied-up position.
I love reflections of sunlight off pool water onto a ceiling - especially before knowing that's what they are the way ignorance of how something works/happens tends towards the bliss of the magickal.
